Specification of Letters Patent.

, Patented Jan.2l, 1908.

Application filed October 2%. 1907- Serial No. 398-874- To all wlwpg'it mag concern:

Be it-Rnownthat I, HENRY AIKEN, of Pittsburg, in the county of Alle heny, State of Pennsylvania, have invente a new an of which the foldrawings, forming part of this speci cation, in which T Figure lis a top plan view of my improved side frame; Fig. 2' is a side elevation of the same partly broken-away; Fig. 3 is a central cross section, and Fig.4 is across section in the journal box portion. My invention relates to the class of side frames forvehicle trucks, and is designed to provide a simple, cheap and strong construction therefor. To that end, it consists in securing the structural members together by casting metal around or through them to form a part of the structure.

.It further consists in ap lying this vfluid F the side frame, also in forming. the central part of'the side frame by a casting which is welded or secured to the structural members by the casting operation.

It also consists in casting the journal box in contact with and thereby securing it to the I a is secured to the otherniembers at the time end portion of the frame.

In the drawings, in which I show the invention as applied to an ordinaryarch bar.

truck frame, 2 represents the upper arch bar 3 the lower arch bar and 4 the tie bar. the form shown, the lower arch bar extends outwardly beyond the end 5 of the'utpper'arch bar, this end 6 of the lower arch arbein referably bent upwardly, as shown in dotte ortion of the tie bar is preferably perforate as indicated at 7. These'endparts are then placed in a suitable mold and the journalbox 8- iscast about firmly in place,

them." The metal forming the lower part of the floor of the j our'nal box flows through the hole or notch of the tiebar, thus securing it while the journal box mold is preferably arranged to form an upward ex.,

tension 9 of the cast metal which surrounds and incloses the end portions pf the two arch bars. This fluid metal will flow into the gap between the end 5 and the bent-u portion 6, and firmly secure these parts. box-may otherwise he journal be-of any ordinary or desirable ty e, solong as the fluid metal flows aroun and secures the structural memhem of tlie frame in'place.

"casting of general rectangu To form the central portion of the side frame, including the truck columns, I also rtion in one preferably form this central 1 shape, as

shown at 10. The upper leg of this castan' g 1 preferably surrounds and incloses the centra r arch bar,

orizontal ortion 11 of the while its ower leg portion similarly surrounds and incloses the central portions of the'lower archfbarand the tie bar. This lower leg of the castingis also preferably provided W1th perforated side lugs 12, to form a securing means for the spring plank orpther' portion. The side portions of this casting may be provided with recesses or holes to lessen its weight. v,

The advantages of my invention will be apparent to those skilled in the art. I The use of. bolts, rivets or other'securing means may be-done awa with and a very strong structure afi rde The castings are preferably ofsteel', and in the act efliorming them, the other arts of the-frame are, secured and stren'gt 'ened, while the cast art is given its desired shape.' 'The'"curna boxes are secured to the frame att e same time that they are cast, thus doing; away with additional securing means-and with the labor and exense incident. thereto. The, center casting of forming it, thus avoidingthe use of securling means at these points. i Y

, The 7 form and arrangement of the side frame may be varied. The casting securing the ends of the arch bars may be formed separately from the, journal box, if desired, so that a separate journal 'box'may be applied; and many other changes may be made without departing from y invention.

I claim:

1. .A truck frame having side frame members secured at their outer ends by a casting formed of fluid metal cast about the parts substantiall as described.

2. A true side frame having a central or intermediate casting secured to the frame parts b flowing the metal about them, substantia 1y as described.

3. A rivetless and boltless side frame having its parts secured by-castingsformed in place about themsubstantially as described.

' 5. An arch bar side frame having the arch termediate and end portions of the arch bars 1 bars secured at their-outer ends b a casting formed about them, substantia 1y as described.

6. An arch-bar side frame having the arch .bars and tie bar secured by castingportions secured together by castings, substantially as described. v

9. An arch bar side frame having the arch bars secured together at the ends by journal scribed.

boxes cast thereon and at the center by a casting secured thereto by flowing the casting about the arch bars, substantially as de- 10. An arch bar side frame having the arch bars and tie bar secured at the ends by casting portions of a journal box about them, said bars being secured at the intermediate part by.another casting having parts surrounding them, substantially as described.

In testimony whereof, I have hereunto set my hand. 1
